A common way that dogs display their love for their owners is by brushing and rubbing their faces against them. This behavior is a means of expressing affection and marking their territory. By nuzzling against you, dogs reveal their vulnerability and trust in you. However, if you observe your furry friend rubbing their face against all surfaces indiscriminately, it might be a sign of an infection, and it’s advisable to seek veterinary attention.
